To all whom it may concern:

Be it known that I, DANIEL W. EDWARDS ,1

a citizen oft-he United States, residing at Rockford, in. the county ofWinnebago and State of Illinois, have invented certain new I tain predetermined articles. Thus in a spe-.

cific aspect, the mechanism is particularly 5 intended for producing holesin railway. ties,

and inserting into such holes, rail-fastening elements, as for example, screw spikes.

In the accompanying drawings, Figure 1 is a side elevation of a car and my improve- '20 ments supported thereby. Fig. '2 is a plan view. Fig. 3 is a section on line 3-3, Fig. 2. Fig. 4 is a section on line -.44 of Fig. 2, showing the upper-portion- Fig. 5V

is a section on line 4-4, Fig. 2, showing the lower portion. Fig. 6 is a section on line 6- 6, Fig. 2. Fig. 7 is a sectiomon line 7 7,

Fig. 6. Fig. 8 is .a-section on line aa, Fig.

5. Fig. 9 1s a view looking atthe face of the wrench socket as shown in Fig. 3. o

Similar reference numerals deslgnate corresponding parts in all the figures of the drawings.

In the embodiment disclosed, a car is provided, comprising a platform 8 supported on wheels 9. Mounted on this car, is a-suitable motor, shown in the form of aninternal combustion engine 10. A friction disk 11 is operated by this motor. V

' Bearings 12 are mountedon'the platform,

'and journaled in these bearings, ,is a transversely disposed shaft 13, on which is feathcred a friction wheel 14. A handle 15 is fixed to the upper end ofra vertical rockshaft 15 that 1s journaled on the platform 4 contiguous to one end of the shaft 13-, and the lower end of this rock shaft is provided with a crank arm 15 connected-to a link 16. This'linkis also. connected to. ajslidlng head 16* carrying a yoke 16 engaged with the ;hub of the friction wheel 14. It' wlll he therefore evident that by turning the handle f 15, the friction wheel 14 may be moved along the shaft 13, and its. eriphery en'- --gaged with the face of the friction disk 11 at difierent distances from its axis of rota- -propelled by the motor, or can be brought secured thereto. 7 carried 'bythe. shaft. '13, meshes with the for the bracket, and rigidly secured to this tion. In order to insure aproper frictional contact between the friction disk and'frigtion wheel, a lever 17 is. provided, which has a link connection 18 with a crank arm 19 carried'bya' shaft 20. The shaft 20 is 6(- providedwith another crank arm 21 hav-. mg a yleldlng connection 22 with. a third crank arm 23. The crank arm 23 is carried by. a rock shaft 24 that also carriesa yoke 25 engaged with the hub of the friction disk, thus providing means, whereby the friction disk may be moved against the periphery. of the friction wheel, or moved out of engagement therewith.

. A sprocket wheel 26 is secured to one of the car-axles 27,- and another sprocket wheel 28 is loosely mounted on the shaft 13. -A 'chaln 28 connects the two sprocket wheels.

The sprocket-wheel 28 is provided with a clutch face 29, and a clutch section 30, slid abiy mounted on the shaft 13, is movable into and out of coaction with the clutch face 29. By thus moving the clutch section into and. out of engagement with the clutch .face 29, it willbe evident that the car may be to a standst ll, without the necessity of stopvpin the motor.

.llfounted onthe car platform, is a bracket 30, .provided with upper and lower bearings 31,11 whichv is journaled a vertical shaft 32 7 having two bevel gear wheels 33. and '34 I A bevel gear wheel 35,

bevel gear .34, and thus transmits motion to the shaft 32. A yoke 36 has its arms-journaled on the shaft 32, respectively above and below the bearings 31 of the bracket 30, said shaft thus constituting a pivot mounting 5 9 yoke 36 is a tubular supportin arm 37 havmgfixed to, its outer end, a ead 38 having a vertical tubular section 39. In the-Q upper'portion' of this tubular section isournaleda tubularshaft 40 having a bevel. gear 41 at its lower end and a spur gear 42' at its upper end. A power-transmitting shaft 43, shown in the present instance, aboveand parallel to the arm 37, isjournaled in the'yoke 36,-and the head 38. The 5 rear 'end of thisshaft .43 carries a bevel gear 44 that meshes. with the bevel gear 33. The opposite end carries a bevel gear 45 that is in mesh with the bevel gear 41.

A tubular tool-supporting sleeve or shaft 46 is journaled in the tubular section, 39 of the head 38, and. is capable of both rotary.

and reciprocatory movement therein. To

the lower portion of this tubular shaftor sleeve 46 is splined a spur gear 47 and a vertical shaft 48, located alongside the sleeve 46 and journaled in the head 38,-has at its upper end a spur gear 49 meshing with the spurgear 42, and at its lower end, a spur reciprocatory spindle 51 splined to the tubular shaft 40. The lower end of this spindle 51, is provided with a suitable chuck 51, by means of which a hole-forming tool, such as a drill or boring bit 52 may be attached to said spindle. I.

V The upper end of the spindle 51 is rotatably mounted in a collar 53, to which is pivoted a link 54- that is also pivoted to a hand lever 55. The lever 55 is fulcrumed on a standard 56 suitably secured to. the supporting arm 37, anda spring 57, connected to one end of said lever, normally holds the spindle 51 in elevated position. A vertically .reciprocatory rod 58, slidably mounted in guide ears '59, formed on the head, has its lower end offset and formed into a collar 58 that surrounds the lower end of the tool-holding shaft or sleeve 46. A collar 60 ismounted 0n the upper end of the rod 58, and a link61, pivoted to said collar, is also pivoted to a second hand lever 62 fulcrumed upon a second standard 63, suitably secured to the supporting arm 37. A spring 64, securedto the lever 62, serves to also hold thiswlever, and consequently the tool-carrying shaft or sleeve 46 in elevated position. The lower end of the sleeve or tubular shaft 16 has a suitable in-- parts at all times, the front end of said platform is curved and provided with a flanged track 66 engaged by a keeper or clip 67 secured to the underside of the supporting arm 37 Briefly described, the operation of the machine is as follows: The same is mounted on a car track, 'as illustrated, and the motor being in operation, it may be propelled along said track by engaging the clutch section 30 with the clutch face 29, any suitable or well known mechanism (not shown) being emface 29. The supporting arm 37 is swung to one side or the other of the track until the head is properly positioned over a tie. The lever 55 is thereupon depressed, thereby moving the spindle with the hole-form- .ing tool 52, downwardly and drilling or boring the hole, as indicated in Fig 1. When said hole has been formed, the lever 55 is released, whereupon the spring 57 will react and ,elevate the same. The article to be inserted in the hole is then placed therein, and the lever 62 is forced 'down against the action of the spring 54. This will cause the rotating tool-inserting member to be brought down upon the article, as for ex: ample, a screw spike and the same will be driven home. The mechanism can then be swung to the other side of the track, and the operation repeated. To unscrew the devices from their holes, it is only necessary to re-' verse the direction of rotation of the toolholding sleeve or shaft. The entire mechanism can be stopped at any time without stopping the engine by disengaging the friction disk'from the friction wheel.

In this mechanism, it is desired to call particular attention to two features. In the first place, it will be noted that both the holeforming and article-inserting devices are at all times maintained in perpendicular relation to the surface of the track, so that the holes will always be properly formed, insuring the-proper positioning of the articles. This is exceedingly important. Moreover, the structure is very simple, and both the hole-forming device and the article-engaging and inserting means operate on coincidenta-xes of rotation and the spike or article is bound to be driven in exactly the sac line as the hole is bored or formed.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or scope of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is Y 1.
